Beschreibung
Zusammenfassung:	The invention relates to a process for low-temperature separation of air, in which an air separation plant having a first rectification column and a second rectification column is used, the first rectification column being supplied with cooled compressed air and the second rectification column being supplied with liquid from the first rectification column or liquid formed herefrom. By means of a first condenser-evaporator, head gas of the first rectification column is condensed and liquid from the second rectification column or liquid formed herefrom is evaporated, thereby producing a first evaporation product. The invention also relates to a corresponding air separation plant.
